No access to Bootcamp after Mavericks upgrade

Hi Loner T,


Thank you for your help. Here are the answers to your questions:


What was the sequence of upgrade? 10.9.3. followed by Parallels or the other way?


I upgraded to 10.9.3 first.


Where in this sequence did the Bootcamp disappear?


After I upgraded, I tried to connect to the Bootcamp partition via Parallels 5. Wasn't able to connect at all. I then upgraded to Parallels 9, was able to connect, but went right to the blue screen.


What OSX version did you upgrade from to 10.9.3?


I believe it was 10.6.


It is good to see that Bootcamp NTFS is intact and mountable?


Yes, seems to be mountable as I can switch between mount and unmount for Bootcamp.


Can you see files in Bootcamp in Finder? If you have XP installed then it is supported, but new installation of XP is not supported.


Yes, I can see files in the Bootcamp Finder.


Can you post the output of the following two commands?

1. Does Bootcamp show up in System Preferences -> Startup Disk as an option?

2. If you power cycle and use ALT/Option key during power-up, does Windows show up as a selectable option?

3. Using the command sudo dd if=/dev/disk0 bs=440 count=1 2>/dev/null | hexdump -C should show you if there are boot loader issues.


Typically, OSX Disk Utility moves partitions around (for example creating a Recovery partition) which can cause boot issues. 10.6 did not have a Recovery partition.


You may need to use XP Installation media for Windows recovery later, if it turns out that you have boot loader issues.

Yes it does, says BOOTCAMP Windows.


2. If you power cycle and use ALT/Option key during power-up, does Windows show up as a selectable option?


Yes, it does, but then it just does that blue screen cycle.


3. Using the command sudo dd if=/dev/disk0 bs=440 count=1 2>/dev/null | hexdump -C should show you if there are boot loader issues.

What do you advise I do? Not sure how to use XP installation media. Do you mean back-up Bootcamp somehow, reinstall Windows into a new partition, restore back-up, erase old Windows partition? If so, I'm not certain how to do that. Thank you.

Jul 1, 2014 2:12 PM in response to Matt2400

The partition tables are fine, and the MBR 1st stage bootloader's first two lines looks fine, I don't read assembly so I can't say the whole thing is definitely correct. But in any case the fact you get to a blue screen tells me you're getting a bootloader failure at some point after the first stage but before the actual kernel is running. If the kernel got up and running, and it found some problems with the file system, there'd be a minimal rescue environment available to repair the file system. You're going to need a Windows XP install CD/DVD and boot from that and try running Windows Startup Repair. That's completely automatic and doesn't always work, but worth a shot. Next there's bootrec.exe, so you might need to dig around to find a bootrec.exe XP guide, I'm not sure if it's any different between XP and 7. It has options to replace the code in the MBR, and the bootloader, and the BCD. So there's actually a lot of stuff to try before giving up. The fact that the partitions are intact and you can read the Bootcamp volume from OS X makes me think recovery is definitely possible, even if tedious.

Thank you Christopher. I'm not very tech savvy, but I can easily follow instructions. Are there any instructions to your 2 options?


1. You're going to need a Windows XP install CD/DVD and boot from that and try running Windows Startup Repair.


2. Next there's bootrec.exe, so you might need to dig around to find a bootrec.exe XP guide, I'm not sure if it's any different between XP and 7. It has options to replace the code in the MBR, and the bootloader, and the BCD.


Good to hear that there's hope!

Ok guys, I went ahead and backed up the data (made a new image of my bootcamp drive onto an external hard drive). I then deleted the partition and reinstalled Windows XP. I can't seem to restore the image though. I get this error message:


User uploaded file


The size of the old bootcamp partition was 80GB, but I only went with 50GB as the data is only 13GB.

For some reason my first partition (Macintosh HD) is not blue throughout the whole box. Even though it says it has 449GB. Not sure if that matters at all.


I can boot up on Windows using the ALT key when rebooting. However, I can't get Parallels 9 to work either.


Is there anyway to get BOOTCAMP.dmg to take on the new partition I created?


Thank you!

Jul 2, 2014 6:14 AM in response to Matt2400

This is now a larger issue. The OSX NTFS driver is a read-only driver (by default). You are trying to write to a NTFS during the restore, which can cause problems. You have partitions that normally do not show up in DU (like EFI, Recovery, etc.).


If the backup was made using DU's image, and your partition sizes are different, that is another likely issue.


A Windows XP Recovery had a better chance of success, as Christopher had pointed out.


It is likely that something like WinClone can restore bootcamp.dmg, but it is not a free product.

Jul 2, 2014 10:07 AM in response to Matt2400

So you used Disk Utility > Restore to make an image of the Windows volume. Where you lose me is when you say you reinstalled XP, but then fail at restoring. "Reinstalling XP" means using the Windows installer to install it from scratch. "Restore" means restoring it from an image. I don't see how you can reinstall and restore. The restore would obliterate the reinstall and vice versa.


You can't use Disk Utility to image an NTFS volume, and restore it to a partition of a different size. That requires Disk Utility understanding how to resize NTFS, which it doesn't. Disk Utility's image of Windows is a sector copy, so it's a fixed size and can only be restored to a fixed size partition. If you want to do this differently, you need a different utility like what Loner T suggested.


Anyway, backing up was a good idea. Nuking the partition and starting over was not suggested by anyone and now you're in a totally different and more difficult situation because you haven't actually done anything to fix the problem. Merely backing up and restoring isn't going to magically fix that problem.

Jul 2, 2014 10:19 AM in response to Christopher Murphy

The answers to my questions haven't been clear. I went ahead and followed Loner T's link:


http://support.microsoft.com/kb/30765


To be clear, I deleted the old partition and reinstalled Windows XP. I didn't restore Windows XP. I'm trying to restore my disk image (BOOTCAMP.dmg). I think it won't allow it because the disk size is different now (50GB vs. 80GB) and I can't resize the Windows partition for some reason.


Do you guys have a step by step process of the following actions:


1. Resize a partition that can't seem to resize. Using this product: http://www.twocanoes.com/winclone


2. Restoring the disk image (the one I backed up).

Jul 2, 2014 10:39 AM in response to Matt2400

This is what Apple says you have to do to resize a Windows partition. i.e. start over. They don't have any other way to do what you're asking.


Neither Loner T nor I asked you to delete the old partition, yet you did it anyway. So I have zero trust that you'll actually follow directions without skipping ahead or doing something else, making things worse, and then asking for even more help. I think it's inconsiderate to ask for step by step help after having made the situation worse by doing something that wasn't recommended.

Re: Booting Bootcamp partion from restored Bootcamp partition


The partition numbering may not be correct anymore because it uses Partition 3, but now it is 4, because of the additional Recovery HD.


I have not tested this method. Please make sure you have adequate backups of MAC OS X and Windows.

Jul 4, 2014 1:24 AM in response to Christopher Murphy

I went to a tech place today and they had everything repaired in a hour (better than before). I would recommend this over these forums to anyone. There are no set qualifications to give advice on here and you will most likely end up in a worst position. People misdiagnosing your problem and throwing any solution at it. Christopher Murray has no idea what he's doing. I would consider another profession or if this is a hobby try a new hobby.
